Brazilian cities deploy drones and cleaning projects to boost public health and infrastructure

The Federal District health department has begun using drones to apply larvicide in hard‑to‑reach areas, aiming to curb Aedes aegypti mosquitoes and reduce dengue risk across dozens of neighborhoods.

In Várzea Grande, municipal crews are carrying out a multi‑day "VG em Ação" programme that includes tree trimming, debris removal, sidewalk painting and traffic‑safety upgrades such as speed‑bumps and improved lighting in several districts.

Meanwhile, Varginha’s city government has launched a combined weeding and asphalt‑repair operation, deploying heavy machinery in seven neighborhoods and on a main avenue to clear vegetation, fix road surfaces and improve pedestrian safety.
